I have a homebrew chest freezer in the garage, and a very understanding wife.

I am going to guess the problem is that the fridge has a 'freon' leak.

This leads to lack of oil in the freon line to lubricate the compressor. Which causes the compressor to overheat, and then a high temp thermostat opens.

The unit cools down, the thermostat resets, and it starts back up again.

The magic temp for overheating the compressor happens to be 8C inside of the fridge.

The reason for the breaker tripping immediately the first few times was from the compressor trying to start. Even though you gave it a couple of days, because of the leak, there is just not enough oil, in the right places, to start right up.

• I am guessing the fix is easy for an appliance guy, a bit of dye to find the leak, solder over it, and recharge.

Best of luck to you and your lager.

Residential Kitchen

In a dwelling unit (residential), GFCI protection is only required for kitchen receptacles that serve the countertop surfaces. There's no requirement to GFCI protect receptacles that serve a refrigerator. Unless the fridge is plugged into a countertop receptacle.

National Electrical Code 2014

Chapter 2 Wiring and Protection

Article 210 Branch Circuits

I. General Provisions

210.8 Ground-Fault Circuit-Interrupter Protection for Personnel. Ground-fault circuit-interrupter protection for personnel shall be provided as required in 210.8(A) through (C). The ground-fault circuit-interrupter shall be installed in a readily accessible location.

(A) Dwelling Units. All 125-volt, single-phase, 15- and 20-ampere receptacles installed in the locations specified in 210.8(A)(1) through (10) shall have ground-fault circuit interrupter protection for personnel.

(6) Kitchens— where the receptacles are installed to serve the countertop surfaces.

Garages, Unfinished Basement, and Other Locations

If the refrigerator is in a garage, boathouse, or unfinished basement. All the receptacles are required to be GFCI protected, so the fridge will have to be plugged into a GFCI protected receptacle.

Why does the fridge trip the GFCI?

Any inductive load when switched off, can produce electromagnetic interference (EMI). This interference can, and often does, trip GFCI devices. Most vapor compression refrigerators have a few inductive loads, any of which could cause the trip.

Is there anything that can be done?

There are devices called snubbers that can be used to reduce, or eliminate the effects of EMI. Installing one between the fridge and the GFCI device, could prevent nuisance trips. The best solution though, is to connect the fridge to a non-GFCI protected circuit.

If that's all it takes, why isn't there already one built in?

While most (all) manufacturers are aware that refrigerators can cause nuisance tripping of GFCI devices, most (none) seem willing to provide a solution. It would be complete speculation for me to try and tell you why they don't care, so of course I'll go through a few possibilities.

• Cost.
  Plain and simple, it costs money to implement a solution.
• Warranties and Operating Conditions.
  Most refrigerators are designed to operate in a kitchen. Running them in dusty, dirty garages and basements could lead to more warranty covered repairs.
